In weight, these ti'out averaged ahout 'i poiunls. The_v were all Tahoe trout, 

 S. henshaio!. These tisheriaen usually started early in the morning, about sunrise, 

 and returned about the middle of the afternoon. One cateh was recorded, however, 

 in which 11 trout were caught between 8 and 11.30 a. m. 



AVhitetish and suckers are abundant in the lake, but have no commercial value. 



The regular flat-bottomed ))oat is used for fishing purposes, and each of these 

 boats is provided with a tank or well in which the trout may be kept alive. The.se 

 tanks will hold from 20 to 120 fish. Almut 80 of these fishing boats were found on 

 the lake, and the average cost was al)Out $30 each, so that the whole represented an 

 investment of §2,400. 



The importance of the Truckee River as a trout stream is suggested from the 

 following record of shipments of trout from towns along its course during the season 

 of 1900: 



This gives a total shipment of 1H>,0S7 pounds for this one season.
